A Justiciar was a high-ranking official in medieval England and other parts of Europe, responsible for administering justice and overseeing legal matters. This role often involved acting as a judge or a chief magistrate, ensuring that laws were upheld and disputes were resolved fairly. The Justiciar played a crucial part in the royal administration, especially during the absence of the monarch. In some regions, such as Scotland, the title of Justiciar was used to denote the chief justice of the realm. The position was significant in maintaining order and enforcing the king's laws, reflecting the importance of a structured legal system in medieval society.
